Introduction:

In-hospital complications frequently occur in hospitalized people over 65 worsening their clinical outcomes. There are, however, few studies on the factors associated with in-hospital complications in elderly patient care.

Objective:

To evaluate factors associated with in-hospital complications in a geriatric acute care unit in Bogotá, Colombia

Materials and methods:

We conducted an analytical, observational, retrospective study in a cohort of 1,657 patients over 65 years of age who received care in the geriatric unit of a high complexity hospital in Bogotá, Colombia. The dependent variable was in-hospital complications and the independent variables, the degree of functional dependence on admission, dementia, nutritional status, social support, comorbidity, and polypharmacy. We used Poisson’s linear regression model to identify associated variables.

Results:

The bivariate analysis showed that functional dependence (PR=2.092, p≤0.001) and malnutrition (PR=2.850, p≤0.001) were associated with a higher rate of hospital-acquired infection. In the multivariate analysis, functional dependence (PR=1.931, p=0.003) and malnutrition (PR=2.502, p=0.002) remained independent factors for in-hospital complications.

Conclusion:

In acute care centers, integral assessment at admission to identify functional dependence and malnutrition predicts in-hospital complications.
